Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 258 Issued at 0245Z on 15 Sep 2017
This report is compiled from data received at SWO on 14 Sep
A. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep
0057 0057 0057 130
B. Proton Events: The greater than 10 MeV proton flux continued a
steady decline from S1 (Minor radiation storm) levels, with a
maximum flux of 77 pfu at 14/0120 UTC and ended the period below the
S1 level. The greater than than 100 MeV proton flux returned to
background levels.
C. Geomagnetic Activity Summary: The geomagnetic field was quiet
until the 12-15 UTC synoptic period, when the CIR and CH HSS caused
an overall response to active levels, followed by minor and moderate
geomagnetic storming conditions during the 15-18 UTC synoptic
period. The escalation of activity was likely due to the the
prolonged period of negative Bz during CIR passage
and CH HSS
onset.
